Questions: Which statement BEST sums up the effects of Tsunamis? They are a source of foods such as fish and sea weed Tsunamis erode, pollute and reshape coastlines. Certain diseases can be traced to tsunamis All of the above

The answer is the second one: Tsunamis erode, pollute and reshape coastlines.

Explanation for each option:

1. They are a source of foods such as fish and seaweed: This statement is incorrect. While tsunamis may temporarily displace marine life, they are not considered a source of food. In fact, the destruction caused by tsunamis can disrupt local ecosystems and fishing industries.

2. Tsunamis erode, pollute and reshape coastlines: This statement is correct. Tsunamis have significant impacts on coastlines, including erosion of land, pollution from debris and contaminants, and reshaping of the coastal landscape due to the force of the water.

3. Certain diseases can be traced to tsunamis: While tsunamis can lead to conditions that may increase the risk of disease (such as contaminated water supplies), they are not directly responsible for specific diseases. The aftermath of a tsunami can create environments where diseases may spread more easily, but this is a secondary effect.

4. All of the above: This option is incorrect because the first and third statements are not accurate representations of the effects of tsunamis.

In summary, the most accurate statement regarding the effects of tsunamis is that they erode, pollute, and reshape coastlines.
